1895 Atlanta Exposition

  Mabel O. Wilson's Negro Building: Black Americans in the World of Fairs and Museums (2012)

  has a description of the exhibits in the Negro building on pages 64-69. Check the footnotes for sources, too. 

  I hope this is helpful.

If you are not already aware, "The official catalog of the Cotton States and international exposition : Atlanta, Georgia, U.S.A., September 18 to December 31, 1895" is available on HathiTrust and it may also list participants in the exposition.

The Prints and Photographs Division of the Library of Congress has custody of a collection of photographs of the Negro Building and exhibits at the Cotton States Exposition. A broader search of the Prints & Photographs Online Catalog indicates that there are other photographs of the Negro Building that are digitized and available online. Please do not hesitate to reach out to the Prints and Photographs Reading Room if you would like more information about this material.
